5 Claims.

My invention relates to skates and more particularly to a type of skate that is commonly referred to as a roller skate.

The object of my invention is to provide a roller skate that is constructed of interchangeable parts of simple design so that the manufacturing costs can be reduced to a minimum.

Another object of my invention is to provide roller skates that may be adjusted both as to wheel base as well as the clamping elements employed in their attachment.

A still further object of my invention is to provide skates that are easily manipulated by the wearer, enabling the skater to start and stop more readily.

Other and further objects of my invention will become more apparent as the description proceeds, when taken in conjunction with the drawings in which:

Figure 1 is a fragmentary cross-sectional view of the skate taken at line ll in Figure 2.

Figure 2 is a bottom view of the skate showing the arrangements of the adjustable parts as shown in Figure 1.

Figure 3 is a cross-sectional view of the skate taken at line 3-3 in Figure 2.

Figure 4 is a top or plan view of the skate showing the toe and heel plate arrangement.

Figure 5 is a cross-sectional view of the clamping arrangement taken at line 5-5 in Figure 2.

Figure 6 is a rear view of the single rear wheel arrangement where the rear wheel is of the swivel type which is allowed to turn, and

Figure '7 is a side view of a part of the skate showing the arrangement of the rear wheel illustrated in Figure 6.

Similar characters of reference indicate corresponding parts throughout the several views and referring now to the same, the character It] shows a longitudinal blade radially disposed in an upward manner at its forward end II. This blade I is provided with longitudinal slots I2 and I2 and an angularly disposed slot l3 near the center which slot I3 is employed for the engagement of a strap or the like (not shown) to assist in the attachment of the device when applied to a users foot.

There are two rollers l4 supported by an axle l which axle I5 is journaled in support brackets l6 and I6. Mounting screws l1 fasten the brackets l6 and IE to the blade l0 through the slot [2 and the horizontal portions of the angular brackets I6 and 16' are attached to a toe plate [8 by means of rivets l9 or in any other l6 and I6 may be moved forward or backward in the slot l2 and fastened in any pre-determined convenient manner. In this manner the brackets position by means of the adjusting screws ll. Obviously as the brackets l6 and [6' are moved forward and backward the plates I8 and the rollers I 4 are also moved forward and backward.

The clamping members 20 and 20' employed to clamp the device to the extended portion of the sole of a shoe (not shown) are actuated by means of a horizontal screw 2| having a right and left hand thread engaging the members 20 and 20'. This screw is rotated by means of a wrench or the like applied to a square section 22 on the extreme end of the screw 2|.

Likewise the single roller 23 at the rearward end of the skate is supported by the brackets 24 and 24' fastened to the blade H] by means of adjusting screws 25 through the slot l2 of the blade l0, and the horizontal portions of the brackets 24 and 24 support the heel plate 26 as shown.

The heel clamps 2! and 21 are adjustably mounted by means of the adjusting screw 28 having a right and left hand thread engaging the clamps 21 and 21' through the slot l2 as shown.

This arrangement and assembly permits the toe plate l8 and the heel plate 26 to be movedforward and backward and the rollers l4 and 23 are thereby automatically moved at the convenience of the user.

In Figures 6 and 7 is shown a modified form of rear roller 29 pivotally mounted by means of a pin 30 which supports the roller yoke 3| to the attaching bracket 32 in a castor fashion. The plate l8 and 26 may be surfaced with a fabric or rubber material as shown at 33 and 34 in Figure 4. This is merely a modification that may be employed if necessary or desirable.

The upwardly extended section I l of the blade I0 is employed by the user in starting or stopping, it acting as a brake when contacting the floor.

It is manifest to anyone familiar with the art that the construction specified incorporates but few parts and the arrangement of the parts is such that they are interchangeable and may be constructed with the minimum amount of dies.

Although I have shown and described a particular construction of my device, it is understood that I may make such changes as I may deem necessary without departing from the spirit of the invention as set forth in the appended claims.

Having th'us described my invention what I claim and desire to secure by Letters Patent in the United States is:

l. A skate of the character described comprising in combination a vertical blade, said blade provided with longitudinal slots a pair of front wheels mounted adjustably in a slot toward the forward end of said blade, a single wheel adjustably mounted in a slot toward the rearward end of said blade, clamping members, said clamping members actuated by. means of a screw engaging the slots in said blade, and sole and heel plate attached to the adjustable mounting for the wheels, to permit longitudinal adjustment of the plates with the wheels on the blade.

2. A skate of the character described comprising in combination a blade, said blade provided with longitudinal slots, a pair of front wheels, said wheels mounted on an axle, mounting brackets, said axle journaled in said brackets, a single rear wheel, an axle supporting said wheel, a mounting bracket, said axle journaled in said mounting bracket, .said brackets adjustably mounted into said longitudinal slots, clamping members, a clamping screw engaging said clamping members, said screw disposed for engagement with the slots in said blade, a sole plate, and a heel plate horizontally disposed attached to said mounting brackets thereby permitting adjustment of said plates in conjunction with said wheels.

3. A skate of the character described in claim 2, in which the rear wheel is pivotally mounted to said mounting bracket th'ereby permitting the single rear wheel to move in a staggered path while in use.

4. A skate of the character described comprising in combination a longitudinal blade vertically disposed, said blade provided with longitudinal slots, an upwardly disposed radial curved portionat the front of said blade, a pair of front rollers, a single rear roller, angular mounting brackets rotatably supporting said rollers, said brackets adjustably attached to said blade by means of screws engaging said slots, a toe plate, a'heel plate, said plates attached to said mounting brackets, adjustable clamp members at both the toe and heel plate, said clamp members actuated by means of a threaded screw through the slots in said blade, and an angularly disposed slot centrally disposed in said blade for the engagement of a strap or the like to aid in the fastening of the skate to the users shoe.

5. A skate of the character described in claim 4 in which the .single roller mounted rearward on said blade is journaled in a yoke, said yoke being pivotally mounted to said mounting bracket to permit a staggered path-of the rear roller when in use.
